An electric kettle has a kettle body and a power supply unit that is configured to supply power to the kettle body. The power supply unit has a plate part, a power supply base and a mounting unit. The plate part has a first surface and a second surface. The power supply base is arranged on a side of the first surface of the plate part and configured such that the kettle body is placed on top thereof. The power supply base has a power supply connection part that is electrically removably connected to the power receiving connection part. The mounting unit is arranged on a side of the second surface of the plate part and configured such that a battery pack is removably coupled thereto as the external power source for supplying power to the heating part via the power supply connection part and the power receiving connection part.

A domestic liquid heating apparatus includes a liquid heating chamber and an electrical heating arrangement arranged to heat, in use, a liquid contained in the liquid heating chamber. The apparatus further includes a handle, for lifting the apparatus, and a user interface, arranged on the handle. The user interface comprises a rotatable dial, operable to select at least one operational parameter of the apparatus, and a display, arranged to display the selected operational parameter.

An appliance coupler water pumping apparatus, used in a liquid heater having a detachable inner container from a base body, is provided. The appliance coupler water pumping apparatus contains a water inlet pipe assembly communicating with an inner portion of the inner container by means of a first through hole and a water pumping pipe assembly being used for matching with the water inlet pipe assembly and extracting liquid in the inner container when communicating with the water inlet pipe assembly. According to the technical solution provided in the present disclosure, a user is able to enable the water inside the inner container of the kettle to flow out by means of the water inlet pipe assembly and the water pumping pipe assembly without lifting the kettle, thereby reducing cases of water spillage, avoiding the scalding for the children, elderly people and users with physical disabilities, and achieving high safety.

An electric heating pot including a body unit and a heating unit configured to provide heat to the body unit. The body unit includes an accommodation space configured to accommodate liquid, the heating unit includes a housing formed such that electrolyzed water is disposed therein, and an electrode portion that is disposed in the housing, formed such that at least one region thereof is in contact with the electrolyzed water in the housing, and includes a plurality of electrodes.

A solid-state radio frequency (SSRF) water heating apparatus is disclosed. In embodiments, the SSRF water heater includes a water tank, SSRF generator array and RF sensors enclosed within an RF-shielded cage. The SSRF array synthesizes RF signals in the microwave range and transmits the RF energy through the water tank, exciting and heating the water molecules without direct contact. The RF sensors at the opposite end of the tank sense residual RF energy not absorbed by the water. Control processors regulate the generation and transmission of the RF energy based on the sensed residual energy. The heated water and/or generated steam is piped to hot water dispensers, beverage makers, or steam ovens.

An article of manufacture includes a wall portion having a wall inner surface and a wall outer surface, a base portion having a base inner surface and a base outer surface, at least a portion of the wall portion and the base portion forming a vessel to retain fluid therein, at least part of the base portion configured to receive heat, and a plurality of shaped portions with at least three sides extending above, each shaped portion of the base inner surface including at least three sides and polygonal shaped tops, each of the plurality of shaped portions capable of supplying heat from the sides to fluid adjacent to the sides, the plurality of shaped portions including the polygonal shaped tops to induce creation of a plurality of hexagonal convection cells in contact with a surface of the fluid which increases heat transfer from a heating source to the fluid.

According to an example aspect of the present invention, there is provided a method, kettle and temperature sensor for measuring temperature in a kettle. The method comprises a heatable vessel formed by a bottom (16) and a wall (17) and a mixer tool (3) mounted in the vessel and having a rotation axle (18) in the middle of the vessel, the method comprising providing a temperature sensor, comprising a wireless transmitter (5), a sensor element setup (11, 12, 13, 14) connected to the wireless transmitter (5), comprising at least two temperature sensor elements, a sensor body (10) for the sensor element setup (11, 12, 13, 14), mountable to the mixing tool (3) so that at least the temperature sensor elements (11, 12, 13) are set radially at a distance from the rotation axle (18) of the mixer tool (3) and at different distances from the bottom (16) of the vessel and measuring the temperature within the vessel at least at two points set radially at a distance from the rotation axle of the mixer tool and at different distances from the bottom (16) of the vessel.

An article of manufacture includes a wall portion having a wall inner surface and a wall outer surface, a base portion having a base inner surface and a base outer surface, at least a portion of the wall portion and the base portion forming a vessel to retain fluid therein, at least part of the base portion configured to receive heat, and a plurality of shaped portions with at least three sides extending above, each shaped portion of the base inner surface including at least three sides and polygonal shaped tops, each of the plurality of shaped portions capable of supplying heat from the sides to fluid adjacent to the sides, the plurality of shaped portions including the polygonal shaped tops to induce creation of a plurality of hexagonal convection cells in contact with a surface of the fluid which increases heat transfer from a heating source to the fluid.
